Abstract
An electronic assembly contains a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point and a contact clip bridging the interruption point. The contact clip is manufactured without a preload, as a thermal fuse. The contact clip has a multiple bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder. The contact clip further has a fixing limb with a limb end seated in a circuit board opening. The limb end of the fixing limb is oversized relative to a circuit board opening, and a deformation being imparted to the contact clip, with an internal preload being generated.
Claims12
An electronic assembly, comprising:
- a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point, said circuit board having a circuit board opening formed therein;
- and
- a contact clip bridging said interruption point, said contact clip being manufactured without a preload, as a thermal fuse, said contact clip having a multiple bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder, said contact clip further having a fixing limb with a limb end seated confined within said circuit board opening between an entrance and an exit of said circuit board opening, said limb end of said fixing limb being oversized relative to said circuit board opening namely said limb end having a width being wider than a width of said circuit board opening, and a deformation being imparted to said contact clip, with an internal preload being generated, said fixing limb further having an S-shaped bent limb section disposed completely outside a confines of said circuit board opening.
An electric motor of an adjustment system, comprising:
- an electronic assembly, containing:
- a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point, said circuit board having a circuit board opening formed therein;
- and
- a contact clip bridging said interruption point, said contact clip being manufactured without a preload, as a thermal fuse, said contact clip having a multiple bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder, said contact clip further having a fixing limb with a limb end seated confined within said circuit board opening between an entrance and an exit of said circuit board opening, said limb end of said fixing limb being oversized relative to said circuit board opening namely said limb end having a width being wider than a width of said circuit board opening, and a deformation being imparted to said contact clip, with an internal preload being generated, said fixing limb further having an S-shaped bent limb section disposed completely outside a confines of said circuit board opening.
A drive of a motor vehicle, comprising:
- an electronic assembly, containing:
- a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point, said circuit board having a circuit board opening formed therein;
- and
- a contact clip bridging said interruption point, said contact clip being manufactured without a preload, as a thermal fuse, said contact clip having a multiple bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder, said contact clip further having a fixing limb with a limb end seated confined within said circuit board opening between an entrance and an exit of said circuit board opening, said limb end of said fixing limb being oversized relative to said circuit board opening namely said limb end having a width being wider than a width of said circuit board opening, and a deformation being imparted to said contact clip, with an internal preload being generated, said fixing limb further having an S-shaped bent limb section disposed completely outside a confines of said circuit board opening.
